Which of the following is a direct result of the respiratory burst by neutrophils?
A
Increased antibody synthesis
B
Decreased phagocytosis
C
Inhibition of complement activation
D
Production of reactive oxygen species
Verified step by step guidance1
Understand that the respiratory burst is a rapid release of reactive oxygen species (ROS) by neutrophils during phagocytosis.
Recognize that neutrophils use the respiratory burst to produce molecules like superoxide anion, hydrogen peroxide, and hydroxyl radicals.
Know that these reactive oxygen species are toxic to engulfed pathogens and help kill and degrade them inside the phagosome.
Identify that increased antibody synthesis, decreased phagocytosis, and inhibition of complement activation are not direct outcomes of the respiratory burst.
Conclude that the direct result of the respiratory burst is the production of reactive oxygen species, which enhances the microbicidal activity of neutrophils.
